Abstract:

The collision of atoms with crystalline surfaces has an analogue in the semi-infinite linear chain of harmonically coupled particles struck on one end by an incident particle. Using this simple model, four different effects have been evaluated and compared with experiment 1 the variation of the condensation efficiency with the mass of the impinging particle and with the strength of binding to the lattice 2 the deexcitation of these atoms immediately after capture 3 the efficiency of energy transfer to the lattice accommodation coefficient for collisions in which capture does not occur and 4 the influence of defects on these quantities.
